Pseudophakic glaucoma

Pseudophakia by itself does not cause ocular hypertension. Pseudophakic glaucoma should be defined as glaucoma that would not be present in an eye if it were not pseudophakic. Ocular hypertension was noted in 15 (9%) of 166 pseudophakic eyes. Only 5 eyes (3%) had ocular hypertension requiring treatment. Three of these eyes (1.8%) had permanent ocular hypertension resulting in chronic pseudophakic glaucoma. This study shows that pseudophakic glaucoma is no more frequent than aphakic glaucoma. Secondary glaucoma in pseudophakic eyes is not always related to the presence of the lens. Pupillary block glaucoma and UGH syndrome are directly related to the lens. Secondary glaucoma by ghost cells and by pigment-dispersion are also in some cases directly related to the lens.
